运行结果

注意事项

注意struts2的json返回结果配置

<package name="default" namespace="" extends="json-default">        <action name="upload" class="upload.UploadFileAction">        <result type="json"></result>        </action>      </package>

注意JSON包的引入commons-beanutils-1.7.0.jar commons-collections-3.2.jar commons-lang-2.4.jar commons-logging-1.1.jar ezmorph-1.0.4.jar json-lib-2.2.2-jdk15.jar
